Sammy Keyes and the Cold Hard Cash

The accidental junior high detective Sammy Keyes is back in her twelfth hysterical mystery adventure!
 
Sammy has three wads of cold hard cash in her hot little hands. An old guy gave them to her. Well, actually, he told her to throw them away. Begged her. With his last dying breath. Which he was taking because Sammy had just scared the life right out of him.
 
So . . . she's got to get this man some help. She's got to do it without being seen. And she's got to figure out how to stash that cash.
 
Aw, c'mon! You'd keep the money too, right? No one ever needs to know. . . .
